This invention relates to improvements in oil burner apparatus and is directed more particularly to oil burner apparatus of the ype adapted for use in connection with stoves, ranges and the like.

The principal objects of the invention are According to one feature of theinvention means is provided for adjusting or leveling the base of the burner to facilitate the provision of the desired amount of fuel and the disposition thereof with reference to the wick or wicks. According to another feature of the invention means is provided in association with the burner for deflecting or directing heat therefrom in such a way that with the burner in operation in a stove or range which is provided with a water front, heat is directed onto the said front and thereby brings about C a more eflicient heating operation than has been heretofore known. and obviates the necessity for heating coils around the burner. A still further ature of the invention is to accurately control he flow of fuel to the burner.

Various novel features and advantages of the invention will be hereinafter referred to in connection with the accompanying description of the preferred form thereof which for purposes of disclosure is illustrated wherein in the accompanying drawings,

'with parts broken away to show a water front 2 such as is located usually inside the front wall of the range and a partition wall 5 4 which usually encloses an oven and separates the same from what may be called the fire-box 6. The burner apparatus ofthe invention', represented at B is disposed within the fire box 6 and may consist of one or more burner units such as shown and hereinafter described. It is common practice to employ a pair of such burners one beside the other in a fire box such as 6. v

' A fuel supply unit is represented by O and may consist of a support 10 which supports a reservoir in the form of a bottle 12 as shown. The bottle is suitably supported so that fuel such as oil may flow by gravity through a pipe 14 to a fuel control apparatus and by means of a pipe or pipes 16 from the control apparatus to the burner apparatus. I i

It is desired and necessary to adjust the height of the reservoir relative to the burner apparatus and may be accom lished by means of the well-known form o apparatus shown.

The burner unit B will now be described in detail and it will be understood that the fuel supply unit 0 and c'ontrol'apparatus C may be connected to one or more of the burner units, such as a pair of units located in the fire box of the range. A

The burner includes a supporting standard such as 20 in which is slidable a rod member 22, the latter being held in various positions by means of a set screw 24 or other suitable means. A flange or ring 19 is provided at the lower side of the standard. A plate or'ring 26 is supported by the upper end of the rod 22 in any suitable manner as by means of webs or arms 28.

A burner base indicated generally by 30 is provided which has an outer pair of annular and upwardly extending spaced flanges 32 and an inner pan of similar annular c annels 33 and 35 for fuel therebetween. The outermost flange 34 and the innermost flange 32 are connected by spacers 36 which are hollowed out to provide passag'eways 38 so that fuel may flowfrom the outer channel 33 between the flanges 32 to the inner channel between the flanges 34. The bottom wall 38 of the base member 30 may rest on'the plate 26 and a web 40 extends across an opening formed between the inner annular flange 34. A clamp screw 42 extending through the web 40- is screw threaded in the rod 22. r

Adjusting screws 44 are in screw threaded relation with the plate 26 so that their upper ends may abut the under side of the portion 38' of the base 30. The channel 35 between the inner flanges 34 has a leveling [surface around the innermost flange 34 and a sump, 52, is formed around the leveling surface, as shown.

With the supporting member 20 resting on the lower wall'7 of the fire box of the range the rod 22 and plate 26 are moved up and down and held in various positions of adjustment so that the burner structure may be located at the desired height. By loosening the screw 42 and manipulating the screws 44 the burner base 30 may be leveled or adjusted so that the level of fuel in the channels of the base may be correct.

The surface 50 acts as a leveling guide .and the base may be adjusted or leveled so that fuel is flush with surface 50 or is at a certain level above or therebelow. In this way it is possible to adjust the base so that the level of 'oil in the channels is substantially the same depth all the way therearound. This is important in burners of the type to which the invention relates and the novel adjusting and level guiding means facilitates the necessary leveling of the oil within narrow limits. After the adjusting of the plate 26 the screw 42 may be tightened to hold the base 30 in adjusted positions against the screws 44.

Wicks 60 which may be of the usual material and circular in shape are disposed in the fuel channels 33 and 35. A pipe 16 is connected by means of a fitting 62 and nipple 64' to the burner base so that fuel may be supplied through the control mechanism. Cylinders 64, 66, 68, and are removably associated with the base 30 and are preferably of perforated metal. A flange 72 rests on the innermost flange 34 and has a central opening 74 therethrough with a flange 7 6 on its periphery which is upturned to embrac the cylinder 64.

The cylinders 66 to 70 inclusive, are supported on suitable shoulders provided on the flanges 32 and 34, as shown, and are also held and an annular air passage 7 6" between the adjacent flanges 32, and 34 leading between cylinders 66 and 68.

A ring 76' rests on the upper ends of cy1-.

inders 66 and 68 to close the passageway therebetween while a disc 78 is sup orted by the upper end of the inner cylin er 64. This latter disc is preferably made from some non-metallic heat resisting material and may be in the form of a flat disc. One or more ears 77 and 79 may be carried by the members 76 and 78 for engaging with adjacent cylinders and function to hold the cylinders in their desired concentric relation.

A deflector 80 is associated with the upper side of the burner and in the preferred form of the invention has legs or supports 82 which rest on the ring 7 6 The deflector 80 has a central plate portion 84 and a flange portion 86 which extends upwardly and outwardly and then downwardly. This maybe called a deflecting flange.

With the burner installed in a' range after the manner shown and described the base 30 is adjusted so that the level of fuel in the channels is of uniform depth. The wicks 6O absorb fuel and when lighted the cylinders are heated so that air is drawn upwardly through the central opening 74 and annular opening 76". The plate or disc 76' and the ring 78 at the upper side of the burner cause air flowing upwardly in the central opening and annular passageway to be directed outwardly through the walls of the cylinders so that the air mixes with combustible gases for the combustion.

The deflector 80 at the upper side of the burner is constructed and arranged to deflect heat outwardly onto the water front and the side wall of the oven. This is much desired and tends to prevent heat from flowing upwardly until its effect has been directed to those parts of the range which it is desired to heat.

Ordinarily, to heat water in a range of the type shown, a coil is placed around the burner. With the deflector of this invention however, it is possible to direct heat onto the water heater or water front and in that way the burner apparatus functions to heat the water as well as to heat the range.

The control apparatus C consists of a hollow member 90 having a lug 92 which'is slidable on a supporting member 94 and an adjusting screw 96 is provided for holding the member 90 in various positions of adjustment. A valve body 98 one for each burner unit where more than one are em- 102 screw threaded in the upper side of the body 98 has a valve stem 10a in threaded engagement therewith, the lower end of which is preferably pointed so that when moved toward and away from the upper end of the bore 100 the flow of fuel past the valve is controlled. An operating member 106 which may be in the form of a disc is carried bythe member 104 by the means of which the valve 106 is turned in one way or the other, and a pointer 108 is associated with the handle or member 104 for registering with graduations on a plate 110.

At the discharge side of the valve the pipe 16 is connected thereto by means of any suitable connection such as a coupling 18.

7 Each of the valve bodies 98 has on its dismeans of the vents the lines 16 between the valves and burner units are vented at all times and the ends of the pipes 112 are disposed above the normal level of fuel in the channels of the burner units so that fuel from the burner will not flow upwardly through the pipes. In this way it is possible to bring about a uniform flow of fuel from the valves and burners at the desired controlled rates.

In order to secure the members 20 in place and hold the burner units against shifting in the fire box there is provided a clamp bar 21 the opposite ends of which overlie the flanges or rings 19. A clamp screw 23 passing through the bar and in threaded engagement with the part 7 of the range is employed to cause the bar to bear on the rings with a clamping action.

The various novel features of construction and arrangement constituting the invention will be apparent from the foregoing description of the present preferred form thereof and pointed out in the appended claims.
